Natural alumina is corundum, molybdenum hardness of 9, cubic zirconia molybdenum hardness of 8.5, but from the point of view of industrial wear-resistant ceramics wear-resistant use, is not the higher the better, but also look at the ceramic toughness, hardness and toughness should be high in order to say that the best wear-resistant ceramics. Not that zirconia ceramics are not as good as alumina ceramics, zirconia ceramics at high temperatures under the lattice phase is very stable, reduced to room temperature zirconia ceramic lattice is damaged. Therefore, at room temperature on the pure alumina and pure zirconia, alumina hardness is higher, the theory is also more wear-resistant. But alumina wear-resistant ceramics is a mixture, it is after artificial ingredients and then dry pressure molding, sintering 1680 ℃ and become, not pure pure corundum. So look at the ceramic alumina content, some manufacturers have 85% alumina ceramics, 92% alumina ceramics, 95% alumina ceramics, 99% alumina ceramics and other ceramics, Jingcheng wear-resistant ceramics in this wear-resistant ceramics industry is a very deep research is very professional, Jingcheng wear-resistant ceramics Rockwell hardness of HRA82-90, fracture toughness KIC ≥ 7.5Mpa.m1/2, hardness is second only to diamond.
Toughened alumina ceramics is based on alumina to increase a certain amount of zirconia ceramic ingredients, wear resistance and toughness between alumina ceramics and zirconia ceramics, because Jingcheng zirconia ceramics price is higher, the user a one-time investment is relatively large, the use of the most manufacturers are mainly European and American enterprises and the Australian BHP Billiton and other large groups.
